CAR-VESTI BUtE.

Patented April 30, 1907/ Application filed June 30, 1906. Serial No. 324.142.

To alt whom it may concern:

Beit known that I JOHN KREHBIEL, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio; have invented certain new and useful Improvements in Car-Vestibules, of.

roads Where short turns and curves are frequent and where it would be impossible to use vestibule trains asbrdinarilyconstructed owing to such turns.

.One of the objects of the invention is to provide a very flexible connection between the vestibule and car and to so pivotally con nect the two that in going around a sharp turn the vestibule may swing quite a distance laterally to prevent breaking-its connection with the vestibule of the next car and may more closely follow-the curve. of the track. 4

It is also an object-of the invention to so i construct the vestibule as to form a closed compartment connected to the body of the car by an unobstructed passage the width of which is not affected by the swinging of the vestibuleand which vestibule and body by being so pivotally connected and arranged form a jointed car.

A further object of the invention is to provide means for hanging the bellows connection which will prevent wearing and cracking of the leather and to provide certain other new and useful features in the construction, arrangement and combination of parts, all as hereinafter more fully described reference bein had to the accompanying drawings, in which Figure 1, is a side elevation of one end of a car embodying the invention; Fig. 2, a horizontal section of the same; Fig. 3, a transverse'section; and Fig. t," a detail showing a portion ofthe car in longitudinal section.

1 is the body of the car havin a roof portion 2 projectin beyond the bod and forrning a cover for t eclosed in vestibule 3 which is supported upon the supporting latform 4 projecting from the end of the .car odyl Beneath this platform is the car truck 5 pivotally attached thereto by a king bolt 6 extending through the platform, and the floorof the vestibule is formed with a rojecting semicircular portion7 through tlie axis of which the bolt 6 projects to pivotally. attach the vestibule to the car-body. From the base of the semi-circular projection the edge of the vestibulefloor' extends outward at an angle thus leaving an open space 8 at each side of g the projection, between the end9 of thecar body and the inwardly slanting walls 1001" the vestibule which walls meet the sidewalls 11 at an obtuse angle and'form awalled in compartmenthaving a door 12 in one side and an open end 13 adapted to be secured in any desired manner to the open'end of'the I vestibule of the next car.

. The space 8 is filled and closed to exclude the dust, dirt etc, by a bellows connection 14. between the walls 9 and 10. The loop portions or folds 15 of the bellows are formed of strips of flexible material and the inner edges of these strips are secured between the outer edges of. strips of sheet metal 16 each folded longitudinally upon itself with a. vertical rod 17 inclosed and secured in its inner looped end, which rods project upwardly and downwardly beyond the'ends of the" sheet metal. The upper ends of said rods are bent to form hooks -18 to hook over a semi-circular supporting track 19 carried by the vestibule to turn therewith and supported concentric with the axis of the pivot thereof or the king bolt, and the lower projecting ends of said rods engage the inner side of a similar track 20 secured to the vestibule floor concentric with the semi-circular portion thereof and at a short distance outside the edge of said portion. The lower ends of the sheet'metal loops 16 rest and slide upon the lower track and the bellows are thus supported and guided and the flexible material protected and prevented from cracking. Shields of sheet metal 21 are secured to the outer surface of the side space 8' at the outer side of the bellows to protest and 'form a wind shield for the bellows and a vertical wall connecting the inner end of each wall lOwith the end of the car bodyto posite end wound upon a suitable vertically to the inner end ofthe wall 10 and at its opextending spring actuated roller 24. Shields secured to the wall 9 of the car body form a casing for the rolls and also form a casing for the door leading from the car into-the passage 22 the floor of which is made level by extending the car floor into said passage and forming it to fit the curve of the projection 7. The drawbar "26 is preferably pivoted upon the king bolt 6, and thus in going around a curve in the track, the draw bar, truck and vestibule all turn upon the'same center, the draw bar and vestibule turning together.

By pivoting the truck and vestibule upon the same center, the vestibule is permitted to follow as nearly as possible, the curve ofthe railway track and thus a vestibule train of vestibule.

long cars may be run upon a track having short turnsand curves, and the pivot being in the center of the passage 22, said passage will not be narrowed by the turning of the As the vestibule turns upon its pivot the curtain at one side of the passage will be unwound from its roll a short distance and the curtain at the opposite side will be automatically wound upon its roll by the action of the coil spring which turns said roll in one direction, and the curtains are thus drawn taut atall times. t Having thus fully described the invention, what I claim is 1. The combination with a carbody and a truck at one end of said body to support the same, of a vestibule and a king bolt to pivot-" ally a tach body) 2. The combination with a car body,'of a the truck an'dvestibule to the i supporting platform extending from one end havinga center pivot bearing adjacent to theend of the body, and a vertical pivot bolt ex tending through said bearing and through the platform and bolster of the truck.

4. The combination with a car body, of a vestibule pivotally attached to the end of the body in the longitudinal center line thereof and with a space between the end of the body and the vestibule to permit said vestibule toturn on its pivot, side walls for the vestibule, and yielding means connecting said side walls and the end of the body to close said space.

5. The combination with a car body, of a vestibule pivotally attached to the endof the body in the longitudinal centerline thereof and provided with a portion formed concentrio with said pivot, and a projecting portion on the car body formed to conform to the curve of the concentric portion of the ves-tie bule.

6. The combination with a car body, of a vestibule, a longitudinally extending semicircular portion on one'end of the floor of the vestibule forming a passage connecting the car-body and vestibule, a vertical pivot located in the axis of said semi-circular extension for pivotally attaching the vestibule to the body, and flexible walls connecting the body and vestibule and extending along the sides of said extension to form the side walls of said passage.

7. The combination with a car body having a pivot bbaring at one end and a truck beneath said end to support the body, of a vestibule having a pivot bearing concentric with the bearing on the body and the pivot bearing of the truck, a bolt engaging the bearings therefor in the vestibule body and truck, and a draw bar pivoted upon said bolt.

8. The combination with a car body, of a vestibule having a longitudinally extending semi-circular extension at one end, a pivot in the axis of said extension toattach the vestibule to the body, rigid walls on the vestibule extending from thebase of said. extension outward, a flexible wall at each side of said extension connected at one end to the body and at the o posit'e endto the inner ends of the rigid wal s, and means for yieldingly holding said yielding walls drawn taut;

9. The combinationwith a car body, of a vestibule pivotally attached to one end of said body with a space at each side of said pivot between the body. and vestibnle, fixed vertical side-walls for the vestibule, vertical flexible walls attached at one end to the fixed walls and forming a passage from'the car body to the vestibule, and spring actuated rollers carried by the body to which rollers the opposite ends of the flexible walls are secured.

10. The combination with a car body and roo a vestibule attached thereto with a space be- Y tween, of a bellows within the s ace to close the same consisting of folds of exible material, rods secured in the inner loops of said folds and projecting therefrom at each end,

and tracks to engage the projecting ends of said rods and guide and support the folds.

11. The combination with a car body and.

a vestibule attached thereto witha space between, of a bellows within the space consisting of outer folds formed of strips of flexible material, loops of sheet metal secured to the inner edges of said strips, and tracks to guide and support the upper and lower ends of said loops, I
